SDD Speeds not up to snuff

Which SSD do you have? I don't usually use that app for benchmarking so I'm not au fait with what results to expect for various SSDs, but those figures seem to be in SSD-land to me.

If it's a higher-end SSD then maybe it's being limited by SATA 3Gbps? What hardware are you using?

Yeah, no surprises then IMO. The desktop Nehalem-class CPU generation's platform was SATA 3Gbps only, and yours looks mobile so I wouldn't expect it to be better. Someone else here may be able to cast further light on your SSD performance figures, but to me they look like they're in the realm I'd expect, ie. making the most of SATA 3Gbps.

If I'm correct, then you're getting the kind of performance anyone would expect from an SSD, and just because SSDs are available that perform faster on more ideal kit, it doesn't necessarily mean you'll actually notice the difference in most uses. Furthermore, the Samsung 840 PRO SSD I have makes full use of SATA 6Gbps yet I've never seen it push ~550MB/sec in a real world scenario (which is what ATTO's benchmark consistently says); commonly >150MB/sec, sometimes I see peaks of 370MB/sec. At the end of the day, that data has to go somewhere, and if that destination can't handle that level of throughput (say the data needs to be decompressed first, or is being copied to a HDD - my WD Black 1TB peaks at about 180MB/sec), then figures like 550MB/sec are pretty meaningless.

Oh ok I wasn't sure if I was SATA 6GBPS or 3. If I'm 3GBPS then these speeds are much better then my old 500gb standard drive.

My computer's load times are now 18.09 seconds from cold boot to password 40.39 seconds from cold boot to being able to launch programs in windows.

Before it was a few minutes (at least 3-5) before i could launch anything in windows confidently like my cpuid hardware monitor
